Dispersive analysis of Λ b → Λ(1520) local form factors

open access: yesJournal of High Energy Physics, 2023
We perform an analysis of Λ b → Λ(1520) local form factors. We use dispersive techniques to provide a model-independent parametrisation of the form factors that can be used in the whole kinematic region.

Rare Decays at LHCb

open access: yesMoscow University Physics Bulletin, 2022
The Standard Model (SM) of particle physics is the most advanced theory describing the behaviour and interactions of elementary particles. Despite passing an impressive amount of experimental tests, several deviations from the SM predictions have been observed in recent years in measurements of observables related to rare $b$-hadron decays, prompting ...

Renormalisation group analysis of scalar Leptoquark couplings addressing flavour anomalies: emergence of lepton-flavour universality

open access: yesJournal of High Energy Physics, 2023
Leptoquarks with masses between 2 TeV and 50 TeV are commonly invoked to explain deviations between data and Standard-Model (SM) predictions of several observables in the decays b → cτ ν ¯ $$ b\to c\tau \overline{\nu} $$ and b → sℓ + ℓ − with ℓ = e, μ ...

Rare φ decays

open access: yesThe European Physical Journal C, 2003
The Kloe experiment has collected an integrated luminosity ~ 500 pb–1 up to now, which means ~ 1.65×109 φ decays. The huge amount of events allowed us to measure rare φ decays. We measured the radiative decays of the φ meson into π0, η and η′(958). These measurements are relevant to assess the mixing in the pseudoscalar nonet as well as to evaluate the

Recent results from CLEO collaboration [PDF]

open access: yes, 2001
Recent CLEO results on beauty and charm meson decays presented at the International Conference on Flavor Physics (ICFP2001) are discussed. The results include exclusive rare B decays (B to PP, PV, VV, \phiK^(*), l^+l^-K^(*)), inclusive b to s \gamma, and

Rare b decays meet high-mass Drell-Yan

open access: yesJournal of High Energy Physics, 2023
Rare b hadron decays are considered excellent probes of new semileptonic four-fermion interactions of microscopic origin. However, the same interactions also correct the high-mass Drell-Yan tails.

Rare B decays [PDF]

open access: yesProceedings of The 13th International Conference on B-Physics at Hadron Machines — PoS(BEAUTY 2011), 2011
Rare radiative, leptonic and semileptonic B meson decays are valuable probes of physics beyond the Standard Model. This talk reviews the sensitivity to new physics of observables related to two rare B decays to be measured in the near future at LHC, B(s) -> mu+ mu- and B -> K* mu+ mu-.
